Fluid pressure is force exerted per unit area. It increases with depth due to the weight of fluid above, creating hydrostatic pressure.
Công thức
The calculator applies P = P₀ + ρgh
- P
- P₀ + ρgh — P₀ + ρgh
Hướng dẫn từng bước
- 1Enter fluid density, gravitational acceleration, and depth
- 2The calculator applies P = P₀ + ρgh
- 3Results show pressure at depth
Ví dụ có lời giải
đầu vào
ρ = 1000 kg/m³ (water), g = 9.81 m/s², h = 10 m
Kết quả
P = 98.1 kPa gauge pressure
Absolute: 199.2 kPa
Lỗi thường gặp cần tránh
- ✕Confusing gauge and absolute pressure
- ✕Using depth instead of vertical distance in pressure calculations
Câu hỏi thường gặp
Why does pressure increase linearly with depth?
Each additional meter of fluid adds the same weight per unit area, creating linear pressure increase.
What's the difference between gauge and absolute pressure?
Gauge pressure measures above atmospheric pressure; absolute pressure includes atmospheric contribution.
